DEVICE AND METHOD FOR AUTOMATIC CONTROL OF SCHEDULED VESSEL MOVEMENT Russian patent published in 2014 - IPC B63H25/04 G05D1/00 

FIELD: transport.

SUBSTANCE: system includes receiver (1) of satellite navigation system, route selector (2) with outputs of the set path angle (PA) signal and the set angle φ_set of course angle, adjuster (3) of rudder displacement angle δ_set, steering gear (4), adjuster (5) of propeller shaft rpm n_set, propeller shaft drive (6), adjuster (7) of maneuvering device rpm n_man, maneuvering device (8), comparison unit (9), differential unit (10), control law correction unit (11) for rudder displacement angle δ, propeller shaft rpm n_set, maneuvering device rpm n_man, unit (12) of path angle (PA) vector position limit values four sectors, control ratio generator (13) and vessel (14) which all are interconnected. The system implements standard and precise control of vessel movement depending on results of comparison of difference between path angle (PA) from satellite navigation system receiver (1) and the set course signal φ_set from route selector (1) with constant C and on position of path angle (PA) vector in corresponding zone of path angle (PA) signal four limit values, thus determining adjustment ratios for each of three channels of vessel control.

EFFECT: higher accuracy and safety of scheduled vessel movement control.
